COlN-ACTUATING ATTACHMENT FOR PHONOGRAPHS.

SPECIFICATION forming part of Letters Patent No. 428,751, dated May 27, 1890.

Application filed February 3 1890. Serial No, 339,069. (No model.)

posit of a suitable coin, and especially to an attachment of this class intended to be operated in connection with a phonograph.

Our invention consists in the novel constructions and combinations hereinafter fully described, and specifically pointed out in the claims.

The object of our invention is to provide a suitable device by which the phonograph may be exhibited and heard by any one upon the deposit of a suitable coin.

Referring to the accompanying drawings for a more complete explanation of our invention, Figure l is a vertical section of the main case A, showing the interior parts. Fig. 2 is a plan of the top of the case. Fig. 3 is a perspective View looking from underneath of the means for establishing and breaking the bearing-passages. Fig. 4. is a plan view of the rollers a and a and a horizontal section of the coin-passage a. Fig. 5 is a plan of the arm P of the phonograph and the arm at of the disengaging-lever M.

A is the main box or casing, upon the top of which is a casing A, in which the phonograph, unnecessary herein to show in full, is contained.

In the top of the box A are the several openings or slots at, in which the coins are to be put. Coin-passages a communicate with these slots,.said passages being formed by a stationary back wall a and a movable or swinging front wall or strip a said last-named wall being pivoted below at the point a and having its top free, so that said wall may swing to or from the fixed wall, and is held to a normal position by a spring a Near its lower end the swinging wall a carries a roller a. Opposite this roller and below the end of the stationary wall is a roller 07, the faces of both rollers being suitably grooved and standing normclly separated and in direct line with the open bottom of the coin-passage, whereby the coin drops into and between the peripheries of the two rollers.

B is the motor of the phonograph, to which the circuit-wires b are directed from the battery I). These wires are so directed as to include the rollers a and a as electrodes normally separated. The motor-shaft C carries on its top the usual sheave or pulley c, from which a belt "extends to and operates thephonograph. Upon the same shaft 0, but within the box, is a pulley 0. Along the back of the box is mounted longitudinally a shaft D, having upon it the pulleys d, corresponding in number to the coin-passages. This shaft also carries a pulley cZ,to which a belt (Z extends y from the pulley c 011 the motor-shaft, whereby a rotary motion is imparted to the shaft D. From the pulleys (Z of said shaft extend belts (1 down to each of the rollers a below, whereby said rollers are rotated. \Vithin the box and suitably located with respect to each swinging wall a are a series of catches E, to which the circuit-wires Z) extend, thereby making said catches electrodes of the circuit. The circuit-wires I) also extend, as shown, to the bottom of the movable walls a? of the coin-passages, whereby said walls are formed into electrodes. Upon each wall is a springcatch F in such a position that when the wall is moved away from the stationary wall the latch will engage the catch E.

The operation of the mechanism as far as described is as follows: A coin dropped into one of the slots a passes down through the coin-passage and, dropping between the rollers a and a serves as an electrical connection between them and closes the circuit. This sets in operation the motor, which thereupon rotates roller a and which has the effect of positively forcing the coin between the two rollers, whereby the swinging wall a is forced over until its latch F engages catch E. The coin, being fed down through between the two rollers, no longer acts as a circuitcloser; but the circuit is still closed by the latch and catch and the phonograph mechanism is set in operation.

To accommodate the rollers to different sizes of coins, the boxes in which the rollers a are mounted may be made adjustable, as shown.

Now, in order to hear the phonograph, we

have the following construction: Under the top of the case A and just to one side of each coin-passage is a fixed plate G, having a hole in it, and with this hole communicates a short tube II, passing through the top of the box and having connected with it the hearingtube I, which hangs down in front of the box.

J is a swinging plate having connected with and opening through it a flexible tube K, which thence extends upwardly through the box and communicates with the spectacle of the phonograph through a tube common to all the tubes K. The plate J is held normally in such a position that its tube K, opening through it, is out of align ment or communication with the aperture in the upper plate G and with the tube II of said aperture. This normal position of the plate J may be maintained in any suitable manner, as by means of a spring or by reason of the position and flexibility of the tube K, connected with it, so that when thrown out of position the constrained position of the tube K will cause the plate to return to its normal position.

Upon the end of the plate J is a small contact-piecej, with which the top arm j of the swinging wall a is adapted to come in contact when said wall is moved over.

The operation again is as follows: \Vhen the visitor deposits his coin in one of the slots, he applies the proper hearing-tube I to his ears. The movement of the swinging wall a of the coin-passage, as heretofore described, and which closes the motor-circuit to set the machine in operation, also, through its arm j coming in contact with the lug or projection j, swings the plate J over, whereby its tube K is brought into alignment or communication with the tube II and thehearingtube I, so that the sound of the phonograph is transmitted to the ears of the visitor. \Vhen the wall a is released, as we shall presently describe, the plate J returns to its normal position, carrying the tube K out of alignment with the tube II, whereupon the sound is no longer conveyed.

The release of the wall a? is accomplished by the following mechanism: The latch F has an extension f, and with this atrip-bar L, extending over all the latches, is adapted to come in contact. This bar is connected by a link Z with one end of a pivoted lever M, the other endof which has extending upwardly from it an arm on, the top of which is provided with a pivoted contact'piece on, which is so hinged as to move only in one direction and is cont-rolled by a spring m P is an arm, which projects rearwardly from the spectacle-frame, and is adapted by the movement of said frame to come into contact with the piece at of the arm m. Now, when the spectacle-frame has reached the limit of its forward movement, and the operation should cease, the arm I comes in contact with the piece m, which is unyielding in this direction. This contact forces down the arm n1, swings the lever M, lifts up on the link I, and throws the inner end of the trip-bar Ii downwardly into contact with the extension f of the latch F, thereby releasing said latch from the catch E, whereupon the spring a returns the swinging wall a to its normal position and the circuit is broken.

The mechanism for returning the spectacle for a repetition of the operation we have not herein deemed it necessary to illustrate, as it forms a portion of a previous application for a patent, Serial No. 33-l,190, filed December 18,1889, and it is necessary herein only to state that when the spectacle reaches the end of its travel suitable automatic means are employed for returning it to its first position for a repetition of the operation, and in this return the arm P does not interfere with the contact-piece m, which simply yields before it without affecting the connected mechanism.

It will be observed that in the construction of the hearing-connections herein described a desirable object is effected of having a series of slots, so that more than one person can hear the phonograph at one time and yet each be required to deposit his coin. He cannot take advantage of the deposit of anothers coin, because the plate J, in connection with each coin-passage, operates independently of its neighbor, and each only is set in operation upon the deposit of a coin in its own passage. Therefore if but a single coin be deposited. the plate J of that particular coin-passage alone is operated, the other plates J remaining in normal position, with their tubes K out of alignment with the tubes II, so that even if another person applies a separate hearingtube I to his ears he cannot 'hear the phonegraph, as the sound is cut oil by the plate J.
